Ecorel Easy 803M T4 is a high-reliability leaded solder paste for the defence and aerospace industries. It uses a classic Sn63/Pb37 alloy with a 183°C melting point.

Key Features of Ecorel Easy 803M T4 Leaded Solder Paste

• Sn63/Pb37 alloy, 183°C melt
• Type 4 powder (20 to 38 micron)
• Perfect for defence and aerospace

Built for Harsh Environments

This paste withstands high thermal profiles. In addition, it works with a range of conformal coatings. As a result, it helps mission-critical electronics survive in harsh conditions.

Fine-Pitch Printing

The Type 4 powder (20 to 38 micron) supports ultra-fine pitch printing. So it gives the precision that modern military-grade boards need.

Bright, Easy-to-Inspect Joints

The Easy series chemistry gives robust wetting and a stable reflow process. Therefore, you get shiny, high-quality joints that are easy to inspect.

Why Choose This Leaded Solder Paste?

It comes in a 500g jar and is a preferred choice for legacy systems and high-reliability hardware. For example, it suits sectors where lead-free options do not meet strict thermal and mechanical stress requirements.

Because the Sn63/Pb37 alloy has a single melting point, it also melts and solidifies cleanly. That helps you get consistent joints from board to board.
